Saw this last night in London and it is fucking brilliant (Anvil and Cauldron played short sets as well!)- a film based on the band and how they have struggled to make it big. Comes across like Spinal Tap but far better as you know it's real and heartwarming to see they still believe! There's a bit of footage of them playing Sweden Rock with a close up of Tyrant (Nifelheim) headbanging on the barrier as well! Definately worth going to see when/ if it's in a cinema near you.
